Basic Knowledge Points of Trace Moisture Tester
Trace moisture tester is widely used in electric power, petroleum, chemical and pharmaceutical, food and solar panel cutting fluid and other fields. Today Shanghai Dan Ding for you to explain the basic knowledge of trace moisture tester, the following is mainly introduced to the trace moisture tester characteristics, preparation for use, as well as common problems, causes and solutions:
Features of trace moisture tester
Small size, light weight; with Chinese display titration process, Chinese and English input and output.
Colour LCD display, graphical interface, simple and convenient operation, easy to grasp.
LCD screen directly displays dew point, micro water (ppm), ambient temperature, ambient humidity, time and date, battery power and so on.
Touch screen input, just a click can independently complete the complicated testing process.
Preparation before use
I. Handle the electrolytic cell: Specific operation: Shake the electrolytic cell gently for a few times, so that the water on the inner wall of the cell bottle is fully absorbed by the electrolyte, and then put the electrolytic cell into the holder, turn on the stirring switch, adjust the stirring speed, so that the liquid surface forms a small vortex, insert the measuring electrode plug and electrolytic electrode plug into the corresponding socket of the main unit, and make good contact with it, and turn on the electrolytic switch.
Note: In the state of over iodine, the green lights of the measurement signal indicator and electrolysis signal indicator are all off, only one red light is on respectively, and the digital display does not count.
Second, adjust the balance of the electrolyte: specific operation: if the electrolytic cell is still in the depth of the over-iodine state, press the start button, through the hole in the middle of the sampling plug injected into the electrolytic cell below the level of liquid for several times, injected at any time at any time to observe the colour change of the electrolyte until the electrolyte becomes light yellow, the measurement signal lamp and electrolysis signal lamp green lamp with an indication of the counter began to count until. To be counted to stop, and then stop stirring, pick up the electrolytic cell gently shake a few times, again so that the water on the inner wall of the cell bottle is absorbed, the end point of the alarm can be calibrated.
Third, calibration: specific operation: after the electrolyte is stable, use the micro-sampler to extract a trace of distilled water, wipe the needle with filter paper, press the start button, injected below the liquid level, the instrument starts counting, reaches the end point, the display of the amount of water, the continuous calibration of the 2~3 times, the count value is in the range of the requirements, indicating that the instrument is accurate.
Note: When calibrating with distilled water (100%), the allowable error is within ±10%.
